Parts for your 2007 Toyota Kluger-Throttle position sensors

2007 Toyota Kluger Throttle Position Sensor (TPS)

Is a throttle position sensor relevant to the 2007 Toyota Kluger? Yes. Toyota’s own technical literature confirms it. The Kluger with the 3MZ‑FE V6 uses ETCS‑i (Electronic Throttle Control System–intelligent), which incorporates dual throttle position sensors inside the throttle body, providing VTA1/VTA2 feedback to the engine ECU. This is outlined in Toyota’s Repair Manual for Kluger/Highlander (Engine Control – ETCS‑i, Throttle Body with Motor) and the Toyota New Car Features (NCF) manual for the 3MZ‑FE. Common Toyota diagnostics referencing these sensors include DTCs P0120–P0124 and P2135 for TPS/APP correlation.

On a 2007 Kluger, the TPS isn’t a separate, adjustable unit like on older cable throttles. It’s integrated into the electronic throttle body alongside the throttle actuator motor. That means it’s absolutely used—but if it fails, the usual fix is replacement of the throttle body assembly rather than just the sensor.

What does the TPS do here? It constantly reports the exact angle of the throttle plate so the ECU can manage fuel, spark, and gearbox shifts. With ETCS‑i, the pedal has its own sensors, the ECU decides the target opening, and the throttle body’s twin TPS tracks the plate position for accuracy and safety. When the TPS data goes skew‑whiff, the Kluger can drop into limp mode, idle rough, surge, or show the MIL.

For servicing a 2007 Kluger, the smart play is prevention. Keeping the throttle body clean helps the sensors read consistently:

• Every 40–60,000 kilometres, inspect and carefully clean the throttle bore and plate with sensor‑safe cleaner. Don’t drench the shaft area.
• Check the throttle body connector and wiring for moisture, corrosion, or strained pins—ETCS‑i is fussy about clean signals.
• If you see codes like P0120–P0124 or P2135, use a scan tool to watch VTA1/VTA2 signals and correlation. If out of spec, replacement of the throttle body is typically required.
• After throttle body replacement or a major clean, perform an idle relearn. With a capable scan tool, run the “Reset/Idle Learn” routine, otherwise, let it idle with all loads off until warm, then a short drive with mixed throttle helps the ECU settle.

Because the TPS is built in, there’s no manual adjustment. Go for quality parts, a fresh gasket, and follow workshop procedure so the ECU’s happy from the first turn of the key.

Popular questions

Does a 2007 Kluger have both a pedal sensor and a TPS?
Yes. The accelerator pedal has its own position sensors, and the throttle body contains dual throttle position sensors. The ECU compares both to make sure the plate angle matches driver demand. If they disagree, it can set a fault and limit power to protect the engine and transmission.

Can the TPS be replaced on its own on a 2007 Kluger?
On ETCS‑i Klugers, the TPS is integrated into the throttle body and isn’t designed to be serviced separately. If the TPS fails or the correlation is out, the usual repair is a complete throttle body replacement, followed by an idle relearn.

What are common signs of a dodgy TPS on this model?
Rough idle, hesitation off the line, random surging, poor fuel economy, and the MIL on. Fault codes like P0120–P0124 or P2135 often appear. If cleaning and wiring checks don’t sort it, the throttle body assembly may need replacing.
